Wacker Chemie AG Hanns-Seidel-Platz 4 81737 München, Germany www.wacker.com PRESS RELEASE Number 11 EUROPEAN COATINGS SHOW 2013: WACKER Presents Novel Polymer Binders and Silicones for Paints, Coatings, Construction, Packaging and Adhesives Applications Munich/Nuremberg, March 19, 2013 At the European Coatings Show (ECS) in Nuremberg from March 19 to 21, 2013, WACKER is showcasing numerous innovations for the paints and coatings as well as for the construction, packaging and adhesives industries. The portfolio ranges from new silicone resins and polymeric binders for high-quality exterior and interior paints and plasters to cyclodextrins as environmentally-friendly process auxiliaries. A new dispersion for intumescent coatings enables steel girders to remain stable for longer in the event of a fire, and a novel silicone resin emulsion permits the formulation of solventfree heat-resistant protective coatings for machine parts, pipes or ovens. Innovative polymer binders allow for water-permeable drainage concrete, low-emission self-leveling flooring compounds and particularly hydrophobic grouts and plasters. Novel surface coating resins are ideally suited for heat-sealable packaging systems and for printing inks in sterilizable food packaging. Hybrid polymers for high-strength structural adhesives and a dispersion for difficult-to-bond surfaces round out WACKER s ECS program. On a floor space totaling 230 square meters, the Munich-based WACKER Group is showcasing its expertise in the paints and coatings, construction, packaging, adhesives and printing inks industries
March 19, 2013 Press Release No. 11 Page 2 of 7 at the ECS 2013. Around 60 technical experts will be on hand for informative discussions with existing and prospective customers. Another WACKER booth in the same hall will further provide visitors with details about the 75 th anniversary of VINNAPAS dispersions. Versatile Solutions for Paints and Coatings The novel silicone resin emulsion SILRES BS 1303 is suitable for formulating coatings with moderately hydrophobic surfaces, but does not show pronounced surface hydrophobicity. Further, the product prevents pinholing of the plaster. The new VINNAPAS LL 3019 dispersion is a versatile binder for high-quality paints and plasters, whether for outdoor applications with high color stability or for lowemission indoor paints (VOC < 1g/l). A sustainable and environmentally friendly alternative for many applications in the paints and coatings industry offers the cyclodextrin technology: The ring-shaped, biodegradable molecules can be used as a process auxiliary in polymerization, for selective modification of thermal stability or as a rheology-control additive. Industrial Coatings for Heat and Fire Protection For more safety in the event of a fire, WACKER presents the novel polymer dispersion VINNAPAS LL 3112 as a binder for intumescent coatings. These special fire-protection coatings encase steel girders, allowing the load-bearing structures of a building to remain stable for longer in case of a fire. The new dispersion now enables highly fireresistant coatings with fire resistance class F120 to be achieved (heat protection for up to 120 minutes). For heat protection of pots, pans, water boilers or ovens, WACKER introduces the silicone-resin emulsion SILRES MPF 52E: The new binder component significantly im-
March 19, 2013 Press Release No. 11 Page 3 of 7 proves the heat resistance of binders and allows low-solvent or even completely solvent-free coatings to be formulated that do not require classification as hazardous substances. Polymer Binders for Construction and Concrete Applications For the first time, WACKER is showcasing the new ETONIS 260 for drainage concrete for road surfacing in railway tunnels durable yet water-permeable. This enables rescue vehicles and fire engines to get to the scene of an accident inside a tunnel quickly and without any problems. Furthermore, it facilitates the transport of moisture from the tunnel, significantly reduces the formation of puddles or backed-up water and makes the surface more durable overall. WACKER is also presenting the new VINNAPAS 5111 L, a VOCreduced powder for the formulation of self-leveling flooring compounds that conform to strict eco-labeling requirements, such as EMICODE EC1+ or Blue Angel. With its VINNAPAS LL 5518 H, WACKER is introducing a particularly hydrophobic novel dispersible polymer powder for applications in damp rooms or outdoors. And with GENIOSIL WP, waterproofing membranes for flat roofs, balconies and terraces can be formulated without the use of solvents. Surface Coating Resins for Packaging and Printing Inks The novel surface coating resin VINNACOAT LL 8100 allows effective sealing of aluminum foils to non-polar plastics such as polystyrene, polypropylene and polyethylene. Thanks to the polymer s inherent elastic properties, no additional plasticizers are generally required in the formulation. That makes it particularly suitable for heat-sealable packaging systems, for instance for yogurt lids or water and juice cups. Specifically for printing inks in sterilizable food packaging,
March 19, 2013 Press Release No. 11 Page 4 of 7 WACKER has developed the new VINNOL H 5/50 A: The surface coating resin is both taste- and odor-free, adheres strongly to a wide range of polymer substrates and offers high pigment compatibility. Additionally, it complies with numerous food-contact regulations. Complex Adhesives Applications For high-strength structural adhesives, WACKER presents its hybrid polymers of the GENIOSIL XB product range: Based on alpha-silane technology, they cure on contact with atmospheric moisture to form thermosets and achieve the high Shore-D strength needed for structural adhesives. They also have no known health risks, meet high technical requirements and give manufacturers wide scope for formulation. For exceptional adhesion on difficult-to-bond surfaces, WACKER shows VINNAPAS EP 8010: The dispersion reliably and permanently bonds paper to challenging surfaces such as polyvinyl chloride (PVC), polyester or polystyrene. It is also characterized by outstanding heat resistance and very high setting speed. The dispersion is thus ideal for high-performance paper and packaging applications, but also for further areas, for instance in laminated products for car interiors. Note: Press releases are available with detailed information on the products mentioned in the three areas of expertise. Visit WACKER at the European Coatings Show 2013 in Hall 1, Booth 1-510.
March 19, 2013 Press Release No. 11 Page 5 of 7 Modern buildings often feature steel skeletons but when the temperature reaches 500 C, steel frames soften rapidly. To prevent them from buckling within minutes during a fire, they are provided with special fire protection coatings, allowing them to resist a fire for much longer. The new VINNAPAS LL 3112 binder ensures significant foam development in these coatings, coupled with improved adhesion and strength (graphics: Wacker Chemie AG). SILRES MPF 52E silicone resin emulsion is a new binder component for heatresistant coatings. The waterbased product permits the formulation of low-solvent or completely solvent-free coatings, and is a reliable coating for pipes, plant components, or pots and pans (photo: Wacker Chemie AG).
March 19, 2013 Press Release No. 11 Page 6 of 7 Water-permeability test: Open-pored concrete modified with ETONIS 260 facilitates the transport of moisture (left), while on conventional solid concrete, water builds up and runs off slowly (right). This results in far fewer cracks forming in the new concrete and augments its resistance to frost and road salts (picture: Wacker Chemie AG). Depending on the formulation, tiny holes can form in exterior plasters, a phenomenon known as pinholing (see photo on left). As the photo on the right illustrates, using the new SILRES BS 1303 silicone resin binder avoids this problem (photos: Wacker Chemie AG).
